My name is Terry Quatrani and I am the Rational Evangelist at IBM. I must confess that I am also a modeling bigot. I started modeling in 1988 using a GE proprietary methodology that eventually became the Object Modeling Technique (OMT). In the early 90s I moved on to the Objectory and Booch techniques. I watched UML being born and followed its progress as it matured into UML 2. Over the years I have found two main benefits to modeling. The first is communication. When you have a model you have a visual representation of your system that... [More]

What does agility look like, and how do we measure it? Agility is about changing rapidly and therefore a truly agile project or organization should accommodate changes more easily. Consequently, improvements in agility are best measured by gauging the cost-of-change trends in software baselines. Improvements in these change trends are best achieved when integration testing largely precedes unit testing. A well-accepted tenet of software engineering governance states, “The later you are in the life cycle, the more expensive things are to fix.”... [More]

Walker Royce on Software Econometrics An expert describes a new approach to software project management Imagine you’re lucky enough to take a eight-week tour of Europe. How do you begin making plans? It might be fairly easy to determine your starting point, and where you’ll eventually end the journey. The more you think about it, you’ll certainly imagine a sequence of smaller trips to famous cities, mountains, seaside resorts. But as you scope out the general profile of your tour, would you plan every meal, every evening stroll, every purchase... [More]

Change is the only constant in the world, there’s no doubt about it. Today more than ever, businesses must face – and effectively manage – rising change and complexity. Uncertainty is everywhere we look. From marketplace shifts to surprise disruptions, managing this new reality is not an easy task.

The world is not just getting flatter,
it’s getting smarter. And changes in our phone usage can be seen as the
archetype of how technology is driving the new smarter planet. The smartness
quotient in the phones is no longer driven by hardware (which gets rapidly
standardized) but rather by the number of applications that can be accessed
with the phone. However developing applications for the diverse platforms such
as Android, iOS, Windows Mobile and others, has become a herculean task. These
platforms offer endless possibilities for... [More]

Transforming the enterprise through agility How communications service providers can use enterprise architecture in an agile way Every day, communications service providers (CSPs) around the world perform a balancing act between the need for new business initiatives and technology versus the need to contain costs and ensure overall efficiency. Data traffic is expected to increase 26x by 2015, leading to a compulsion to boost capital expenditure (CapEx) in order to build additional capacity. CSPs will be forced to find new and innovative ways... [More]

For the past decade, agile methods have proved beneficial for helping Information Technology (IT) software teams deliver, on schedule, high quality software that satisfies stakeholder needs. Software teams pursue agile methods because they need a process that can respond efficiently to change to the product under development. Agile methods afford more flexibility compared to traditional plan-driven approaches, which lock in the project details early and are less able to adjust to stakeholders’ evolving needs, market changes, and unplanned...

We all hope for substantial gains from IT investments, but imagine achieving a return on investment (ROI) of more than AUD $4 million within the first year. That's a pretty impressive result! Like most organizations today, Australia and New Zealand Banking Group Limited (ANZ) faced significant pressures to reduce costs. The bank had a substantial increase in the demand for its IT services and realized that simply adding more resources to keep up with the demand was not the answer. Instead, they needed to achieve greater efficiency and... [More]

The world has officially gone mobile. It has done so in ways that we could not even have conceived of only a few years ago. Today, there are more smartphones and tablets sold than all of the PCs in the world put together , and in certain countries mobile devices have replaced cash . They have created a vibrant app economy with almost 500,000 new jobs. And a mobile startup goes from zero to a one billion valuation in less than two years. Mobile development has not been confined to just the individual or consumer market. It has also been a key... [More]

For most organizations, innovation and competitive differentiation go hand in hand. But often an organization’s ability to quickly and proactively respond to change driven by market drivers, customer demands and even regulatory compliance can be limited due to: The lack of visibility into the enterprise to identify the effects, costs and risks of change, and to gain an understanding on where to invest time/resources, on which initiatives, and in what order A complex infrastructure and older technologies that hinder business innovation and...

The IBM Software Technical Summit in China, which was held earlier last month in Beijing, was heavily geared toward the IT practitioners. This was easily observed from the participant demographics. At the conference, I was more likely to run into a young IT professional wearing casual outfits than a business suit. I admit, the choice of clothing was partly due to the artistic DNA of this city, which is the cultural center of China and nurtures more musicians than any other place in the country. But the point is, if you are an IT practitioner... [More]
